The yen should strengthen by as much as 20% to around 130 per U.S. dollar, former Japanese vice finance minister for international affairs Tatsuo Yamasaki said as USD/JPY returned near 162 on July 6, arguing that level better reflects Japan's fundamentals. Yamasaki also said intervention remains possible as early as mid-July, underscoring the risk that Japanese authorities could step into the market if one-sided yen weakness persists. At the same time, Monex Group's Jesper Koll and Blue Edge Advisors' Calvin Yeoh said USD/JPY could reach 200 or higher if the Bank of Japan falls behind on policy normalization, highlighting the widening debate over how far yen weakness could run before officials act.
